Statement I: In a region where uniform electric field exists, the net charge with in volume of any size is zero.
Statement II: The electric flux within any closed surface in region of uniform electirc field is zero.

A

Statement I is true, Statement II is True, Statement II is a correct explanation for statement I.

B

Statement I is true, Statement II is True, Statement II is Not a correct explanation for statement I.

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
A
(Moderate) Electric flux within any closed surface in region of uniform field is zero because the total number electric lines of force entering the closed surface equls that leaving the surface. Hence, from Gauss's theorem the net charge enclossed within such a closed surface is zero.
